CentOS Graphics issue on Dell Optiplex 760's using intel driver

[Clint Dilks]

Hi Everyone,

I am writing to ask if other are experiencing lot of problems with the 
CentOS 5 intel X Driver on Optiplex 760's?

In a batch that my work have just purchased I am finding that I can't 
get a resolution better than 1280 x 1024 @60Hz and that even when I get 
this resolution (according to the monitor) software tools like xrandr 
might report the resolution as 1024 x 768 @ 30Hz.  It also seems that 
there are no wide screen modes supported.

So firstly can anyone confirm of deny that this is a known issue?  And 
does anyone have any suggestions on how to improve the issue?

Just out of interest I tried installing Fedora 11 and this increased the 
number of modes available and seemed to make resolution shown is 
software match what the monitor said as far as resolution but still no 
widescreen modes are available.

Thank you for any thoughts or suggestions you have relating to this issue.
